.5" mdf for a single 8" sub?

[evil_lies]

I just got a quad cab Dodge Ram and I want to put a small sub in the storage area under the back seat. I'm trying to keep the box compact. Would .5" mdf be ok for a small sub or will it fall apart? I'm looking at a Tang Band W8-740P. I'm not set on that sub though. The tang band would only be fed like 300 watts.

I wouldn't use anything less than 3/4 mdf for box construction.

I have used it as a skeleton for a fiberglass box, but I agree that straight 1/2 is not the way to go.

If it’s put together well and sealed really good it should work ..look at factory enclosure they are usually if not always thin plastic ..a bazooka tube thin plastic ..the 1/2” is way thicker ...than those ..now the 3/4 would be better

It'll be just fine. Not like your hanging a 50 pound sub and running 3k watts.

Cool. I know I'm really only saving .5". I'm haven't measured how deep I can go. It has a fold out floor that I would like to keep so if I want to keep it as small as I can.

Fiberglass is the way to go with the storage portion. I use the FoxBox in two of mine and I cannot complain. I had sealed setups previously and they were underwhelming.

.5 thickness is completely fine for your particular setup. Its not some 20-35lb sub, its just a tiny little lower powered 8. Just add some bracing and you good.

Double up on the 1/2". Even a little power to a single 8" enclosure, your gonna find it difficult to put screws thru due to the board thiness vs. 3/4".
